Draws print preview of the pgNo-th page to PageRect rectangle of Canvas.

procedure DrawPreview(pgNo: Integer; Canvas:  TCanvas;

  const PageRect: TRVCoordRect);

There is more convenient way to display print preview: TRVPrintPreview component.

The page image is scaled to fit PageRect. To maintain correct proportions, you can use Preview100PercentWidth and Preview100PercentHeight properties.

pgNo must be in range from 1 to PagesCount.

You need to assign source document for printing (AssignSource method) and format pages (FormatPages method) before calling this method.

To draw unscaled page, use DrawPage and DrawPageAt methods.
